Title: A process for improving the properties of synthetic fibres, fabrics, films and moulded articles by the irradiation of ionising rays
IPC: D06M10/08
Filed: 1959-03-24
Abstract: The dyeability and water affinity of fibres, films and other articles made from synthetic linear high polymers is improved by irradiation with ionising radiation to a dosage of 104/107 Roentgens in the presence of or prior to contacting and heating with certain compounds having a three membered heterocyclic ring in which the hereto atom is O, S or N. Specified compounds are ethylene oxide, ethylene sulphide, ethylene imine, epichlorhydrin, 2,4,6-tri(ethylene imino)-1, 3, 5, triazine, polymethylene-N,N1-bisethyleneurea propylene oxide, propylene sulphide, propylene imine, b -butylene imine, 1,1-dimethylimine, and oligomers of ethylene imine.  In examples fibres of polyethylene, acrylonitrile, P.V.C., polypropylene, polyethylene terephthalate and polyvinyl alcohol were exposed to gamma radiation and simultaneously or subsequently contacted with ethylene imine, ethylene oxide, epichlorhyrin or propylene sulphide. The permanent weight increases were measured and the dyeability tested.  Reference has been directed by the Comptroller to Specification 820,120.

Filed: 1962-03-16
Abstract: 976,978. Pulse amplifying circuits. GENERAL ELECTRIC CO. Ltd., W. R. GODDEN, and R. D. NIXON. March 1, 1963 [March 16, 1962], No. 10280/62. Headings H3P and H3T. A valve amplifier for negative-going pulses has a semi-conductor device connected in its anode/cathode path to reduce the standing anode current during periods when no input pulses are received. As shown, four-layer (Shockley) diodes 4 are normally in their high impedance state so as to limit the standing anode current in the pentode 1. When a burst of negative-going pulses is to be amplified, the pulses are applied to terminal 12 so as to trigger the diodes 4 into their low impedance state. The pulses are also fed via a delaying device to terminal 19 so that they are amplified by the pentode 1 and passed to the output terminal 14. The time constant of the circuit comprising capacitor 10 and the pentode 1 is sufficiently long to ensure that capacitor 10 provides the anode current for the pentode during each burst of pulses, diodes 4 returning to their high impedance state when capacitor 10 has discharged. Semi-conductor controlled rectifiers, triggered on their gate electrodes, may replace the Shockley diodes 4.

Abstract: 886,727. Making rolls; rolling; drawing. DALMINE S.p.A. April 1, 1958, No. 10356/58. Classes 83 (2) and 83 (4). In a drawing or rolling device particularly for forming tapered work at least two rolls with axes coplanar have intermeshing formations e.g. teeth which form part of the pass enclosing surface so that the pass channel has a substantially continuous periphery in planes adjacent the plane of the roll axes. Rolls A, B, C of a threeroll rolling stand are each formed by cutting the pass groove from a pair of 60-degree bevels arranged back to back. The flanks F of the meshed teeth form part of the pass-surface as shown in Fig. 2. The drive for rolls B and C may be transmitted through the teeth from shaft 1 or if the teeth are not conjugate the rolls may be separately driven. The rolls may be eccentrically grooved for tapering successive parts of a continuous workpiece, the parts being subsequently separated. Alternatively separate workpieces may be successively tapered or the pass diameter may be maintained constant during passage of the work. In the invention as applied to a drawing device the rolls may either be driven or undriven.

Title: Manufacture of vat-dyestuffs of the anthraquinone series
IPC: C09B5/26
Filed: 1937-04-14
Abstract: Vat dyestuffs of the anthraquinone series are manufactured by reducing a 1 : 3-di-(anthraquinonylamino)-4 : 6-dinitrobenzene compound, in which the anthraquinone radicles may contain substituents, e.g. chlorine atoms or methoxy, phenylamino or benzoylamino groups, to the corresponding 4 : 6-diamino compound, tetrazotizing this to produce the diazo-imide, converting this into a dicarbazole by heating it in an organic solvent of high boiling point, and, if desired, brominating the product.  The products dye vegetable fibres scarlet, brown and violet shades. In examples: (1) 1 : 3-di-(a -anthraquinonylamino)-4 : 6-dinitrobenzene is reduced in chlorobenzene by means of hydrogen in the presence of a nickel catalyst, the product is tetrazotized with amyl nitrite in glacial acetic acid and the resulting diazo-imide is boiled with diphenylamine; the product dyes cotton from an orange vat red-brown shades; (2) the product of (1) is heated with bromine in nitrobenzene in the presence of iodine; the product yields orange dyeings from an orange vat; (3) 1 : 3-di-(51-benzoylamino-11-anthraquinonylamino)-4 : 6-dinitrobenzene is treated as in (1); the product dyes cotton from a red-brown vat red-brown shades; (4) 1 : 3-di-(41-phenylamino-11-anthraquinonylamino)-4 : 6-dinitrobenzene is similarly treated; the product dyes cotton from an orange vat grey shades.  1 : 3-Di-(anthraquinonylamino)-4 : 6-dinitrobenzenes are obtainable by reacting one molecular proportion of 1 : 3-dichloro-4 : 6-dinitrobenzene with two of an aminoanthraquinone or a substitution product thereof, e.g. 1-aminoanthraquinone or its 5-benzoylamino- or 4-anilido derivative, advantageously in a solvent of high boiling point, e.g. nitrobenzene, and in the presence of an acid-binding agent, e.g. sodium carbonate, and of a copper salt, e.g. copper acetate, as catalyst.

Abstract: 1,022,792. Electrophotographic processes. EASTMAN KODAK CO. March 13, 1964 [March 18, 1963], No. 10642/64. Heading G2H. An electrostatic developer comprises a volatile solvent or mixture of solvents containing a solid solute, the resistivity being sufficiently high as not to discharge an electrostatic image. The solvent evaporates after application leaving an imagewise deposit of the solute. The solvent should preferably have a specific resistance of at least 10<SP>10</SP> ohm-cmm and a dielectric constant less than 3, examples being hexanes, heptane, isooctane, mixtures of aliphatic hydrocarbons, kerosene, toluene, xylene, halogenated hydrocarbons such as carbon tetrachloride and fluorinated hydrocarbons. Examples of solute include dyes or polymeric compounds. In one example, an electrostatic latent image, on a photoconductive surface of zinc oxide in a resin binder, was swabbed with developer containing 5 grms. of poly-m-butyl methacrylate in 95 grms. of cyclohexane and allowed to dry. The resulting image was immediately visible by reflected light when viewed through a Schlieren optical system. Image areas may be hydrophilic on a hydrophobic surface or the image areas may be hydrophobic and the non-image areas rendered hydrophilic to permit use in lithoprinting.

Abstract: 630,802. Frequency measurements. PHILIPS LAMPS, Ltd. April 23, 1947, No. 10868. Convention date, Sept. 2, 1944. [Class 37] [Also in Group XL (c)] In a mixing arrangement in which the signals to be mixed are applied respectively to the inner and outer grids of a multigrid valve, the outer grid is biassed so as to be conductive over part of the cycle and an impedance which is high at, the desired combination frequency is included in its circuit. The signal applied to the outer grid preferably consists of short periodic pulses. The impedance may comprise a tuned circuit (Fig. 1, not shown), or alternatively a network having an impedance which is substantially constant over a wide frequency range and comprises series resistance 13 and inductance 14 shunted by a condenser 15. The arrangement may be used to produce a wide range of frequencies by adjustment of the frequency of the signal 8 applied to the inner grid and by utilisation of the beats formed with the harmonics of the other signal. It may also be used for frequency measurement, the source 8 then comprising the unknown frequency. The term in the output due to beating with the nearest harmonic in the pulse train is selected by means of a low-pass filter in the anode circuit cutting-off at half the fundamental frequency of the pulse train, and is measured by known means such as comparison with a lowfrequency oscillator.
